VAPORIZING-TUBE.

SPECIFICATION forming part of Letters Patent No. 632,498, datedSeptember 5, 1899. Application filed March 6, 1899. Serial No. 708,023.(No niodel.)

To all whom, it may concern:

Be it known that I, ARTHUR KITSON, a subject of the Queen of GreatBritain, and a resident of Philadelphia, county of Philadelphia, Stateof Pennsylvania, have invented certain new and useful Improvements inVaporizing- Tubes, of which the following is a specification.

My invention relates to vapor-burnin g apparatus, and is specificallydesigned to produce an improved form of vaporizing-tube.

One difficulty encountered in the use of vapor-burning apparatus inwhich the heat of the burner vaporizes the oil in a vaporizingtube orother chamber is that when poor grades of oil are used a considerablequantity of carbon or other solid matter is deposited in thevaporizing-tube and getting into the discharge-orifice interferes withthe discharge of vapor and the even operation of the lamp. My presentinvention presents one method of overcoming this difficulty, whichconsists in inserting in the vaporizing-tube, near the end having thedischarge-orifice, one or more diaphragms having small perforationstherein. The perforations in the diaphragm have a cross-sectional areawhich is only a minute fraction of the cross-sectional area of thevaporizing-tube. Several of these diaphragms may be used, the total areaof the openings in the respective diaphragms increasing as the distanceof any particular diaphragm from the discharge-opening increases. Thesediaphragms,while effective when placed in an ordinary straightvaporizing-tube, are still more beneficial in their effects when locatedin a portion of the vaporizing-tube raised above the level of the mainbody of said tube.

The preferred form of apparatus embodying my invention is disclosed inthe accompanying sheet of drawings, in which- Figure 1. represents avaporizin gtube, partly broken away,with the cooperating parts of thelamp and the perforated diaphragms shown in position. Fig. 2 is across-section of the vaporizing-tube on the line 2 2 of Fig. 1. Fig. 3is a similar cross-section on the line 3 3. Fig. 4: is a detail View ofa bent tube, partly broken away, with the diaphragms in position. Fig. 5is a cross-section on line 5 5 of Fig. 4. Fig. 6 is a cross-section online 6 6 of Fig. 4. Fig. 7 is a cross-section on line 17 17 of Fig. 4.

Throughout the drawings like referencefigures refer to like parts.

The vaporizing-tube 1 discharges into the mixing-tube 2, being suspendedin the lampframe 3. There is a muffler 4: placed over the mouth of themixing-tube, and the vaporizingtube has a discharge-opening 5. The usualstrainer of wire-gauze 6 may be inserted in the tube near the dischargeopening, and back of that I place a diaphragm '7, having a minuteopening 8 therethrough. Back of this may be placed another diaphragm 9,having two or more similar openings 10 10.

In the modification shown in Fig. 4 the'diaphragms are all located inthe portion 1 of the vaporizing-tube, which is bent to one side of andabove the main body of the tube, but which is preferably parallelthereto.

The mode of operation of my invention is evident. The openings 8 and 1010 having an area which is but a minute fractional portion of thecross-sectional area of the vaporizing-tube, said diaphragms operate tokeep back the carbon and other deposited matter and prevent itaccumulating over and in the discharge-openings 5. It is evident thatbut a small portion of the solid matter will get by the first diaphragm9, and this will undoubtedly be deposited before it gets to the seconddiaphragm 7, and so on, as many diaphragms as are necessary beinginserted.

Where the diaphragms are inserted in the raised portion 1 of the tube,as shown in Fig. at, there is a further tendency for the carbon todeposit in the lower main body of the tube, and so the discharge-orificeis still further protected from clogging. When the tube anddiaphragm-openings become clogged up, so as to interfere with theoperation of the tube, the diaphragrns may be punched out and the tubecleaned, new diaphragms being inserted or the old ones cleaned and putback.

The advantages of my invention reside in its simplicity andefiectiveness in protecting the discharge-opening and also in the easewith which the parts may be removed for cleaning or replacement.

It is evident of course that various changes could be made in thedetails of construction above shown and described without departing fromthe spirit and scope of my invention. Difierent forms of diaphragm mightbe employed, a greater or less number than that shown might be used, andthe diaphragms might be used to advantage when difierentvaporizing-tubes are used; but all of these I consider mere changes inform and not in substance.

Having therefore described my invention, what I claim as new, and desireto protect by Letters Patent, is-

1. The combination of a continuous horizontal vaporizing-tube, havingits end containing the discharge-opening bent above the level of butparallel to the main body of the tube, and a removable verticaldiaphragm near the discharge end thereof, which diaphragm has one ormore perforations whose total cross-sectional area is a minute fractionof the cross-sectional area of the vaporizingtube.

2. The combination of a vaporizing-tube, anda series of diaphragms nearthe discharge end of the tube, said diaphragms having perforations whosecross-sectional area is a minute fraction of the cross-sectional area ofthe vaporizing-tube, the total area of the perforations in respectivediaphragms increasing as the distance from the discharge-openingincreases.

Signed by me at Philadelphia, Pennsylvania, this 24th day of February,1899.

ARTHUR KITSON.
